Analyze Nutritional Data and Generate Insights

Nutrition Analyzer analyzes dietary and nutrition data, identifies nutrition patterns, evaluates nutritional status, and produces personalized nutrition-improvement recommendations. It has five functional modules: nutrition trend analysis (macro/micronutrient trends, calorie-source shifts, meal timing and frequency patterns, food-category preferences); nutrient intake assessment against RDA/AI standards (macronutrients including fat-type breakdown, vitamins A/C/D/E/K and the B-complex, major and trace minerals, and special nutrients like omega-3s, choline, CoQ10, and phytochemicals); overall nutritional status assessment (nutrient density score, food diversity score, balanced-diet score, dietary-pattern identification such as Mediterranean/DASH/vegetarian, and deficiency/excess risk flags); correlation analysis linking nutrition to weight, exercise, sleep, blood pressure, and blood sugar; and personalized recommendation generation covering nutrient adjustments, food substitutions and pairings, eating-habit changes, and reference-only supplement suggestions.

Use this when the user needs nutrient intake, dietary-pattern, or nutrient-target analysis, macro/micronutrient assessment, RDA comparison, dietary trends, or dietary-improvement suggestions, or wants nutrition data correlated with exercise, sleep, or chronic-disease data. It carries an explicit medical safety boundary. What it can do: statistics and analysis of nutrition data, trend identification and visualization, RDA achievement-rate calculation, deficiency-risk assessment, general nutrition advice, and checking for supplement interactions. What it explicitly cannot do: diagnose a nutritional deficiency disease, prescribe supplements, replace a registered dietitian, manage severe malnutrition, or assess food allergies. Recommendations are graded into three levels: Level 1 (general, DRI/RDA-based) needs no medical oversight, Level 2 (personalized, based on user data) suggests consulting a dietitian, and Level 3 (medical, involving disease management or supplementation) requires physician confirmation and must never have its dosage self-adjusted.

Reads a main nutrition-tracker file plus daily meal logs, correlating against profile data (weight, BMI) and fitness, sleep, hypertension, and diabetes trackers where available. The core RDA achievement-rate formula divides actual intake by the RDA value, classifying the result as severe deficiency (under 50%), insufficient (50-75%), approaching target (75-100%), adequate (100-150%), or excessive and exceeding the safety upper limit (over 150%). A nutrient density score weights vitamin achievement at 40%, mineral achievement at 30%, and fiber achievement at 20%, with a penalty deduction for excess saturated fat, sodium, or added sugar; a separate Healthy Eating Index, adapted from HEI-2015, scores 0-100 across food-group adequacy (fruit, vegetables, whole grains, dairy, protein, plant protein, fat-quality ratio) and moderation components (refined grains, sodium, added sugars, saturated fat, each scored so less is better). The output report includes trend direction and magnitude per nutrient, an RDA achievement table, a food-category breakdown table, meal-timing statistics, an overall diet-quality score, key insights, and a prioritized action plan with concrete swaps, such as specific fruits and vegetables to add for potassium, plus a monitoring schedule for tracked biomarkers like serum vitamin D.

Built-in danger-signal detection flags both nutrient excess, such as long-term vitamin A over 3000mcg or sodium persistently over 2300mg, and deficiency, such as vitamin D under 10mcg/day with serum levels under 12 ng/mL or iron under 6mg/day for women of childbearing age, as well as abnormal calorie intake (sustained under 1200 or over 3500 calories/day) and abnormal eating patterns (fiber under 10g/day, added sugar over 25% of calories). It references public standards including China's Dietary Reference Intakes, the US Dietary Guidelines, USDA FoodData Central, WHO nutrition guidance, and a supplement-interaction database.

Users tracking their own diet who want trend analysis, RDA-based nutrient assessment, correlation with other health metrics, and a prioritized, concrete action plan, while being routed to a registered dietitian or physician for anything beyond general, data-driven guidance, especially disease management or supplement dosing.
